When you finish writing the pseudo code for a specific process for which is necessary to write a computer program,
follows writing the algorithm.
The algorithm is a graphical representation of program flow. To write the algorithm we use standard graphic elements
that each of them represents a specific step in the program. Referring to standard accepted worldwide and understandable to all programmers.
The first element is a Line of program flow that connects graphic elements and ends with an arrow in that direction in which the process (program) continues. Specifies the sequence of steps in the algorithm, and the program.Other graphical elements are understandable by themselves:
Elements Start and End program are identical and mark the beginning and end of program.
Element Input represents data entry from the keyboard or any HD, CD or any other place where data is retrieved.
Element Operations is a step in which individual actions are executed in the pseudo code or the program (adding two numbers, assigning values to a variable, etc.).
Element Condition represents prerequisite step for conditional branching in program,
within it you ask questions (If.. then .. else), and determine future course of the program based on the answers. The default is that an affirmative answer extend program down and negative to the left or right. Also the question must not be ambiguous.
Element Output is the output data, write results in a variety of devices, usually monitor, printer ...
Other graphic elements used in making Algorithm you can see attached to this page.
All the best,
